Club Nintendo hacked in Japan

Nintendo's consumer rewards club hacked in Japan

Nintendo has announced (translated via Kotaku) that the Japanese version of its consumer rewards site, Club Nintendo, has been hacked. The company had a large number of access errors on July 2, which led to a full investigation. Nintendo found 23,000 unauthorized log-ins out of 15 million attempts between June 9 and July 4.

Club Nintendo sites in other countries were unaffected, but members in Japan may have had their full names, addresses, and phone numbers compromised. Nintendo is strengthening its security to prevent another intrusion and is asking Club Nintendo members to change their passwords via email.

Being that this was their Club Nintendo system in Japan and not their online infrastructure, Nintendo is still the only player out there not to get hacked in that arena.

And 23,000 unauthorized out of 15 million attempts is actually pretty damn impressive for the security. That's a positive hit of 1 out of every 652 attempts. A basic dictionary attack will almost always yield more than that.
